To aZZ whom it may concern.-

Be it known that I, JOHN CINNAMON, a citizen of the United States, residing at New Brighton, county of Richmond, State of New York, have invented certain new and useful Improvements in Heating and Ventilating Houses and Rooms, of which the following is a specification.

My invention is designed to supersede the use of stoves and furnaces in heating and ventilating houses which I accomplish by radiation and reflection of heat waves, as distinguished from heating rooms by filling their empty space with air which has been heated.

My invention relates to an improvement in the means and apparatus for heating and ventilating buildings.

The object of my invention is to warm the floor and lower portion of the walls of a room as well as the occupants thereof by heat reflected from a point near the ceiling of said room in contradistinction to the usual method of heating the air and causing that medium to conduct the heat to the walls and occupants, and thereby avoid burning the air and destroying its life-giving qualities.

Another object of my invention is to provide an automatic means of ventilation of the heated room operated by the atmosphere contained therein.

Referring to the accompanying drawings which fortna part of this speciflcation:Figure I is a sectional view showing my invention applied to the center of a room. Fig. II is a similar view showing the invention applied to the corner of a room. Fig. III is an enlarged detail sectional view of the ventilating pipe and automatic valves.

My invention consists, as is shown in the drawings (Fig. I) of an umbrella shaped metallic polished reflectorA placed near the ceiling of the room to be warmed, below which is hung by rods the source of heat B whj c h may be a coil of electrically hmd'v'v ire, a steam radiator or other heat giving source. The center of the said reflector is perforated at (l, and from the perforation extends ventilating pipe D either below the ceiling, or between the ceiling and floor above, to an outlet communicating with the exterior air. A suitable concentric sleeve E around said vent pipe with a space between the two, prevents danger to inflammable material through which it may pass. At the mouth of the perforation in the reflector are placed upwardly opening valves E, E, nearly balanced, but having a slight preponderanceof weight at their inner edges, which causes them under normal conditions to remain closed, thereby shutting off communication between the atmosphere of the room to be heated and the outer air. The upward pressure of any considerable body of warm air under the said reflector is sufficient to open these valves and allow the warm air to escape. Below the source of heat beforementioned with a space between them, is hung by suitable supports, a second smaller reflector or screen G which cuts off the rays of heat, radiated directly downward, and throws them up into the main reflector, whence they are thrown downward as reflected heat.

The shape of my reflector may be varied to conform to the conditions giving greatest efflciency as may be found by experiment and it may be placed at the top, sides or in the upper corner of a room as may be most convenient or desirable.

The action of my device is as follows:The suspended heat radiating device B throws out heat in all directions. The direct downward radiationis interceptedby tlielower reflector eaua thrown up to the mam 't-enctorn, whence together with the other radiated heat received from the radiator it is reflected to the lower part of the room, passing through the atmosphere without, to an appreciable eX- tent, heating it and being absorbed by the opaque objects on which it finally falls. These objects (the floor, furniture, &c.,) having received the impact of the heat rays convert them into obscure heat which is imparted to the air by conduction and convection. As the air becomes heated it rises, and when a sufflcieutquantity has accumulated under the dome-shaped reflector, its upward tendency causes the valves E, E to open, allowing the heated and vitiated air to pass out through the vent pipe D, its place being taken by fresh air which enters the room from the usual openings. By this means I achieve a gentle, uniform heating of the room, remove vitiated air, and avoid drafts, the tendency of the outgoing air being vertical throughout the heated area.

Fig. 11 represents an alternative form of my device adapted to be used at the sides or corners of a room. The action of this form is identical with that of the form described and the lettering of the drawings are alike for similar parts.

Either form of my device may be used to warm the veranda or porch of a house.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In a heating apparatus the combination of an elevated source of heat, a reflector mounted adjacent to said source of heat and constructed to direct heat rays downward past the same, an outlet for the escape of heated air from the reflector and a screen located below the source of heat with a space between them and constructed to intercept direct radiation and prevent escape of heated air down- Ward, substantially as explained.

2. In a heating apparatus the combination of an elevated source of heat, a reflector located adjacent thereto, to direct heat rays downward past the source, a passage for the escape of heated air from the reflector and automatically acting check-valves in the passage to prevent influx of cold air, and the screen located below the source of heat with a space between them to prevent direct radiation and the escape of hot air downward, as explained.
